How about "get fully capable smart phones out of schools now"? This safety argument could still be fulfilled with a cheap, simple phone that allows the student to text / call 9-1-1 and a handful of trusted contacts.
No, I want my children to have access to high precision GPS, bluetooth, hd video and a high speed data connection during a crisis. I'm not worried whether or not the cops will be called. I simply refuse to wait outside for a hour with them while a crazy person shoots up classrooms one by one.
That's our plan. A simple device that allows for emergency use. Call mom, dad, trusted friend, 911. But our kid is young and limits are hard. As they age up, this will evolve.
Or just put voip phones in every classroom for emergencies and ban mobile phones for students. 99.99999% of teachers have a cell phone anyway in the event of a proper emergency.
